To all wizomz'tmay concern.

Be it known that I, FREDERICK A. HART, citizen of the United States, andresident of New Britain, in the county of l-lartfordv and State ofConnecticuahave invented certain new and useful Improvements inTypewriting Machines, of which the follow ing is a specification; j A jJ This invention relates to improvements'in typewriting machines, whichcomprise a paper table that is supported on a paper carriage onwhich ismounted a roller platen to which the paper is fed. The invention relatesespecially to'iinprovernents in the paper tables of suchmachines. Themain object of the invention is to provide such machines with a papertable that is instantly detachable from and attachable to the papercarriage and that is suitable for use in accounting machines in which alarge paper table, that extends to the height of six inches more or lessabove the platen,'

is usually required. 7 r

The invention consists of the paper table that is described and claimedherein.

On the accompanying sheets of drawings on which like reference numeralsdesignate like parts in different views; "Figure 1 is a fragmental rearelevation of a paper table embodying the invention and of the platen andplaten frame of a typewriting machine, the table having right and leftstandards supported by the platen frame; v

The invention is shown as it appears when it is embodied in a Remingtonaccounting machine. It was made especially for use in such a machine,but can readily be applied to others.

This machine commonly has a paper table comprising the plate 10 with apair of hori- Zontally adjustable paper guides mounted on it, the loweredge of the plate being a little below and behind the top of the platen11 and the plate extending upward and backward to a height of about sixinches above the platen, as represented in Figs. 1, 2 and 3. One of thepaper guides is on the left half and the other on the right half of theplate. Only the left guide is illustrated herein. This guide includesthe back or base 12, wing 123, block 14. spring 15. and screw 16 havingthe head 17. The base and wing, 12 and 13, are parts of one piece ofsheet metal bent so that these parts form a. right dihedral angle. Blocklei is fast on base 12 of the guide, closely but loosely fits in slot 18in plate 10, and is it and into the block, under stress so that it drawsbase 12 of the guide against the front face of the plate 10. hen screw16 is loosened the guide may be movedto the right or left, block 1 1sliding in slot 18.

The right guide is symmetricalto the guide shown and above described,andthe block attached to its base fits and slides in slot 18 (Fig. 1) inthe right half of plate 10.

The plate 10 with the guides mounted on it, has been supported inRemington account- .ing machines on standards aflixed to the papercarriage, but has not been detachable from or replaceable on the papercarriage or standards without the aid of a tool. It is desirable todetach the paper table when ever a machine is to be enclosed in adropleaf cabinet, and whenever it is to be put into a case for shipment,and at other times.

Remington-accounting machinesalso include the paper carriage on whichthe platen 11 is mounted and of which the end plates 320. and 21 and.rod 123 are..pa1 ts,.this rod and rod 22, which isthe-al-eed rollrelease rock shaft, extending throughout the length of the carriage androd 23 being fastin the end plates.

Paper tables embodying the invention may b pr vided w h s andards.difiering, nore or le fro th sewh ch sh n n lpan ticularly describedherein; and so as to lit them for use in both Remington and other;

To detach the paper table from the .pape carriage, finger pieces 37 and4 6 of the locking device are pulled forward until the hooks 35 and 51are disengaged fromrod 23,- then the table is turned on rod 22 until theheels of the standards are free from rod 23, and then the table islifted from rod 22. The table is attached to the paper carriage bystanding it on rod 22 so that toes 32 and 4-8 engage the rod asdescribed, then pulling forward the finger pieces of the locking devicesand swinging the table backward, the 1 standards turning on that rod,until heels 33 and 49 of the standards engage with rod 28, and thenreleasing the locking devices, which the springs 41 and 55 instantlythereafter draw into engagement with the rod 23 and so hold that thetable is locked to the rods.

Various changes may be made without departing from my invention.
